Tried the latest git. So far I'm not sure if I like 3.0 over 2.0, so here's a little comparison from my personal point of view.
1) Weather does not work properly.
2) I use "low list" view for TV seasons and I like the way it is done in 2.0 more. I'd like to have both TV banner and logos as in 2.0. And If I choose banners instead of logos, banners appear truncated and if a show has no banner, there is an empty placeholder. 2.0 does not have such issues.
Also I haven't found an option to show a codec flag instead of a source flag as in 2.0.
3) In 2.0 the default submenu item for TV shows was "Latest". Now it is "Titles". IMO it is less convenient because you can get to titles simply by entering "TV shows".
4) Haven't found an option to disable "TV tunes" as in 2.0. And from what I've seen so far it looks like 3.0 has less customization options than 2.0. And many of them are deeply hidden and not intuitive for users who are new with Aeon-Nox.
5) I like the ability to have 2 widgets for both Movies and TV as in 2.0. Also a widget for episodes of currently watched shows is missing. In general, I like the widget set in 2.0 more.
